Root barriers only work if they are correctly specified and professionally installed.
Our consultants have spent the last 12 years working with root barriers, perfecting installation technics and refining how root barriers are specified to ensure they effectively block Japanese knotweed.
PBA Solutions offer market leading Flexi-root barrier and Bio-root barrier products that have a design life in excess of 50 years. Both can be heat welded while the Bio barrier is a permeable dual action barrier having a micro perforated layer of copper sandwiched between two geo membranes. The copper layer inhibits root growth and the geo membranes act as a physical barrier.
